摘要: Center filler plates for mounting on draft sills of railway car underframes are disclosed. The center filler plates have four pockets surrounding a hub. The pockets are shallower than in the prior art, and the walls defining the pockets meet in radii having larger radii of curvature than in the prior art. The shallower pockets and larger radii of curvature facilitate removal of the casting from the molding sand in the cope and drag sections of the mold. The formation of burned-in sand is limited in the present invention, and any burned-in sand that does form is also more easily removed from the center filler plates of the present invention. The base portion of the center filler plates is not as high as in the prior art. The ribs of the center filler plate and the walls of the hub are thicker than in the prior art to provide the needed strength to the center filler plates. In one embodiment, the ribs taper toward the hub, and the hub is shorter than the surrounding web; a tool may be inserted through the kingpin hole, expanded to bear against the tapered surfaces of the ribs; a machine may be used to lift the center filler plate and move it into position on the draft sill. The tool may then be contracted and removed, and the center filler plate may be secured to the draft sill through welding or other techniques.
摘要翻译: 公开了用于安装在铁路车底架的底板上的中心填充板。 中心填充板具有围绕轮毂的四个口袋。 口袋比现有技术浅,并且限定袋的壁与半透镜相比,其比现有技术具有更大的曲率半径。 较浅的口袋和更大的曲率半径有助于从铸模的上模和拖曳部分的型砂中移除铸件。 在本发明中,烧成砂的形成是有限的,并且任何形成的烧成砂也可以更容易地从本发明的中心填料板上除去。 中心填充板的基部不像现有技术那样高。 中心填充板的肋和轮毂的壁比现有技术更厚,以向中心填充板提供所需的强度。 在一个实施例中,肋朝向毂逐渐变细,并且轮毂比围绕的腹板更短; 工具可以穿过主销孔插入,膨胀以抵靠肋的锥形表面; 可以使用机器来提升中心填充板并将其移动到起草条上的适当位置。 然后可以将工具收缩和移除,并且中心填充板可以通过焊接或其它技术固定到通风门。

摘要: A gauge is provided that is useful in measuring the horizontal wheelbase of a railway freight car truck sideframe. The gauge itself is comprised of a main horizontal body section usually of a single piece of aluminum bar stock. A stationary depending leg extends downwardly and is affixed to near one end of the main horizontal body section. A bearing slide assembly is affixed to the main horizontal body section near its other end. A measuring leg depends from the bearing slide assembly and is movable along the bearing slide assembly. An indicator scale is associated with the measuring leg so that its relative position with regard to the main horizontal body can be readily measured from a scale affixed thereon. The stationary depending leg is brought into contact with one edge of a pedestal jaw of the railway freight car sideframe, and the measuring leg is moved into contact along the bearing slide assembly with an opposite edge of the opposite pedestal jaw. A measurement reading of the wheelbase of a sideframe is then made.
